I buy almost all of my produce fresh, but one of the few things I buy canned (shock horror!) is tomatoes.

Before I go any further – BPA

Let’s talk about BPA (Bisphenol-A). One of the main reasons put forward as to why you shouldn't buy food like tomatoes in cans, is that there is a risk of BPA exposure. As tomatoes are acidic, there is a concern about chemicals leaching from the tin liners into the produce. Unfortunately, given the acidity of tomatoes, the main way to mitigate this risk would be to buy tomatoes in glass jars. It seems that no canned tomatoes are sold in BPA-free cans (though there is a problem with that too – as those types of cans may contain another risky chemical – BPS–Bisphenol S). Yet, I still buy canned tomatoes…

So why do I buy canned tomatoes?

Until I can harvest and preserve my own tomatoes (which is going to take a good few months), I’m going to be buying them canned.

I often find the fresh tomatoes sold don't seem to be quite in season, and have been picked far too early. Use them as they are, and the flavour is completely lacking. Take them home and ripen them – and I almost always miss that sweet spot of ripeness and end up with a rotten mess. Tinned tomatoes are canned at the perfect moment and are always full of flavour.

Also – have you seen how much fresh tomatoes cost? At the time of writing this fresh tomatoes are $9.98 a kilo (for those reading from the US, that’s $4.53 a pound). No, not organic tomatoes, just regular tomatoes. That’s about $1.10 to $1.40 for one single tomato. Over a dollar for on tomato. That’s a lot of money. I hate that money has to come into it, but spending $10 on a few tomatoes to make a simple sauce is just not in my budget. I’d rather spend that money on meat.

Canned tomatoes are also peeled, which is a great convenience.

I use tomatoes as the base of so many of my recipes, so it’s handy to always have lots on hand – another reason I like to buy canned.

Yes, the BPA risk is a concern, but given this isn't a significant part of my diet, this is a risk I feel justified in taking.

But what’s in the can?

What I am concerned with, is what is actually in the can. Have you seen some of the ingredients?

I just want tomatoes in my can of tomatoes. Too much to ask for? Fortunately, there are a few brands I've found that do just contain tomatoes…

My advice is to choose a brand that is just tomatoes (no seasoning or herbs – add your own) and check the ingredients carefully.

These are some of the ingredients in some popular brands I've found. Aside from Tomatoes, tomato juice and tomato puree, the brands I looked at also contained:

Firming Agent (509),

Acidity Regulator: Citric Acid (E330)

Calcium Chloride

Here are the brands to choose and avoid

I've highlighted the ones I would use in red. I'd rather give citric acid and the other additions a miss…
